iStockphoto/Thinkstock(NEW YORK) -- There was still no word from the Israeli government Thursday confirming an air strike earlier in the week that targeted a truck convoy in Syria that U.S. officials say was carrying missiles to the Hezbollah in Lebanon.

However, Syria, Iran, Russia and the Hezbollah have all condemned the attack, which Damascus initially claimed was an assault against a scientific research facility outside the capital.

The Hezbollah denied that it was receiving arms shipments from its ally, while the Iranian government warned Israel's action would cause "grave consequences for Tel Aviv."

Moscow, another staunch ally of Syrian President Bashar al-Assad, added that the attack "blatantly violates the United Nations Charter and is unacceptable and unjustified, whatever its motives."

According to U.S. officials, Syria was transporting SA-17s to Lebanon. Meanwhile, there was confusion over whether the Israelis actually attacked a Syrian facility as well as the truck convoy.

In spite of the potential for the two-year Syrian conflict to escalate because of the incident, it's expected that Israel will conduct future preemptive strikes to protect its borders.
